  • Media with controllable refractive properties
    Patent number: 7015865
    Abstract: An apparatus includes a 3D array of circuit elements and control lines for coupling a remote control device to the circuit elements in the array. Each circuit element is configured to transform from one circuit state to another circuit state in response to a change in a control signal received from one of the control lines. The 3D array includes a region that behaves as a metamaterial in a selected frequency when the circuit elements of the region are in one set of circuit states and as a normal refractive medium in the selected frequency when the circuit elements of the region are another set of circuit states.

  • Resonant antennas
    Patent number: 6661392
    Abstract: An apparatus includes an object and one or more sensors located adjacent to or in the object. The object is formed of a material whose dielectric constant or magnetic permeability has a negative real part at microwave-frequencies. The one or more sensors are located adjacent to or in the object and measure an intensity of an electric or a magnetic field therein.
